APPARATUS FOR DYEING SKEINS.

SPECIFICATION forming part of Letters Patent No. 437,173, dated September 30, 1890.

' Application filed May 29, 1890. Serial No. 353,564. (No model.) Patented in France September 4, 1888,11'0. 192,712, and in Switzerland December 24, 1888,1l0. 202.

To all whom it may concern.- I

Be it known that I, CESAR CORRON, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Apparatus for Dyeing Skeins, of which the following is a specification.

This invention is the subject of a patent in France, No. 192,712, dated September 4, 1888, and in Switzerland, No. 202, dated December 24, 1888.

In the dyeing of silk, wool, and other fibrous matter in the form of skeins or hanks it is customary to hang the skeins over bars or skeincarriers. which are laid horizontally across the top of a long vat, so that the skeins hang into the dye contained in the vat while the bars or skein-carriers are held in notches at the top of the vat. A portion of each skein is consequently not immersed in the dye. Inorder to immerse these portions and at the same time to agitate the skeins in the dye the workmen move the bars, successively displacing each oneto a position afew notches in the rear, and simultaneously they grasp the skeins and slide or draw them around over the bar to bring a new portion thereof into the bath of dye. This operation of shifting the skeins is known to the French dyers as lisage. The workmen perform these operationsthe displacement of the bars and the lisage of the skeins-in succession upon the bars from one end to the other of the vat, and then back again, and so on alternately from end to end.

In my United States Patent No. 363,949, dated May 31, [887, is disclosed a machine comprising mechanisms for seizing the bars in succession, lifting them out of their notches, carrying them back to a suitable distance in the rear, and dropping them into othernotches. Mechanism is also provided for turning the bars during the act. of lifting and displacing them in order to effect thelisage of the skeins. Means is provided for throwing this turning mechanism into and out of operation at the will of an attendant. My said machine comprises two carriages traveling on opposite sides of the vat and carrying revolving arms,

on the ends of which are seizing devices for grasping the ends of the skein carriers or bars. As the carriages advance, each bar is engaged and carried upwardly and backwardly or in the opposite direction to the advance of the carriages, being moved through a semicircular arc, and finally dropped into notches in the rear. lVhen the turning mechanism is in operation, the bars are rotated during the operation of carrying them over. The carriages travel back and forth from end to end of the vat.

My present invention provides an improved machine which more perfectly performs the operations essential to the manipulation of the skeins by hand, and is entirely automatic, requiring no hand labor whatever from beginning to end of the dyeing operation, and only such supervision as any dyer must necessarily give to the progress of the dyeing.

To these ends my invention provides a displacing mechanism adapted to move the carriers successively from one position to another over the top of the vat, a turning mechanism for rotating the carriers during their displacement, and mechanical connections constructed to automatically bring the turning mechanism into action during the action of the displacing mechanism in one direction, and for moving it out of action or rendering it impotent to turn the carriers during the travel of the displacing mechanism in the other direction. By reason of this feature of my invention the lisage of the skeins occurs at every alternate displacement of the carriers, and each lisage takes place in the same direction, so that the skeins are caused, as it were, to revolve by intermittent movements upon the carriers, and a new portion of the skein is brought out of the dye at every lisage independently of any attention on the part of the operator, and without the possibility of the lisage occurring in the contrary direction, which would bring again out of the dye the portion which, prior to the previous lisage,

carriers, which are rendered more simple and positive in their operation than in the construction shown in my previous patent.

It further relates to improvements in the construction of the turning mechanism, and to the specific means for throwing this mechanism into and out of action, and to other details and improvements, which will be fully hereinafter set forth.

In the preferred embodiment of my present invention, I provide two carriages traveling on opposite sides of the machine, in the same general manner as in my previous patent, these carriages carrying rotative radial arms, which in turn carry the devices for engaging the ends of the skein-carriers. The two carriages and the revolving arms thereof operate in unison, the arms picking up simultaneously the successive bars and carrying them over in a semicircular path backwardly and finally dropping them into suitable notches formed in a frame placed over the top of the vat. The seizing devices or holders are pro videdwith epicycloidal gearing, by which they remain always with the same side up during the revolution of their carrying-arms. The holders are formed with two pockets or compartments,in one of which turns the rotating chuck of the turning mechanism. This chuck receives rotation through epicycloidal gearin g, being constructed to make one revolution from the instant of picking up a skein-carrier to the instant of redepositing it. The other pocket is empty, and serves only to lift the skein-ca-rriers without turning them. The pockets open at diamctrically-opposite sides of the clutch, so that when the latter is turn ed one side up the empty pocket engages the skein-carriers and simply displaces them with out turning, while when the holders are turned the other side up the opposite pockets receive the skein-carriers and the latter are turned during their displacement by the action of the revolving chucks.

To throw the turning mechanism into or out of action it is simply necessary to invert or revert the holders. This operation is performed automatically at each end of the travel of the carriages through the medium of a throw-over stop mechanism, which communicates motion to the central wheel of the epicycloidal train, which is thereby turned far enough to communicate the half-revolution simultaneously to all the holders. \Vhile the carriages are traveling in one direction the holders simply lift and transfer the skeincarriers without turning them but at the end of the travel of the carriages and the instant before their driving mechanism is reversed to move them back in the opposite direction the holders are inverted, thereby bringing the turning mechanism into elfective action, and during the return travel. of the carriages the skein-carriers are rotated during their displacement.

Such is, in general, the construction of the preferred embodiment of my invention; but

it is to be observed that my invention in its broader aspect is not limited to any particular special construction or embodiments, but is susceptible of being greatly varied, so long as the same general operations are performed upon the skein-carrying bars-namcly, that during their displacement in one direction they are not turned, and during their dis placement in the contrary direction they are rotated to perform the lisage of the skeins.

In the accompanying drawings, which show the preferred construction of my machine, Figure l is a side elevation thereof, partly in vertical section. Fig. 1 is an enlarged fragmentary detail of a part of the mechanism shown in Fig. 1. Fig. 2 is a plan of the apparatus.

A designates a dyeing-vat; 13, a frame mounted thereover, removable therefrom, and centered when in place thereon by having eyes which drop over conical pins (6 a at the corners of the vat, and provided with notched bars b b on opposite sides.

(3 C are skein carriers or bars, which rest in notches in these bars I) Z). The skein-carriers are preferably of the construction shown in Figs. 5 and 6, having end projections c c, which enter the notches and project beyond far enough to be seized by the holders of the displacing mechanism, their intervening portion consisting of bars or wings, one of which projects preferably farther from the center than the other. These two bars or wings of the skein-carriers are placed wide enough apart, by preference, so that by turning the skein-carrier one revolution the skeins will be shifted su'liiciently around the carrier to bring that portion which then was out of the die into or nearly into immersion therein. The skein-carriers are hence essentially flat reels, being made flat in order that they may lie close together, so that as many skeins may be dyed simultaneously in a vat of given length as possible. They are made eccentric or projecting farther to one side of the end portionsc 0 than the other in order to bring the center of gravity below the under side of these end portions and thereby cause the skein-carriers to hang vertically when deposited in the notches and without tending to tilt or oscillate therein. This construction of the skein-carrier is that which is preferably employed in connection with my present invention by reason of its important practical advantages; but it is not essential thereto.

The displacing mechanism for lifting and transferring the skein-carriers is carried by two carriages D D, which travel on longitudinal guides or ways on opposite sides of the vat. The two carriages are arranged exactly opposite one another and travel simul-. taneously and at the same speed. The main frame (1 of each carriage is constructed to slide on a bar a and a shaft F, both extending longitudinally of the vat and constituting the guiding-Ways for the carriages. The shafts F revolve and constitute the drivingshafts for communicating motion to the carriages. On each shaft F is a pinion fiFig. 3, connected to the shaft bya spline or feather, so that it can slide longitudinally. This pinion is mounted on a sleeve f Fig. 2, engaged at its opposite ends by downward] y-proj ectin g arms, forming part of the carriage-frame d, by which it is caused to slide longitudinally on the shaft as the carriage travels. The pinion f gears witha gear-wheel g, fixed on ashaft h, which is mounted in bearings carried by the frame of the carriage, Fig. 1. Fixed to this shaft are two beveled pinions g and h, of which the former meshes with a bevel-gear on a tubular shaft 6, having bearings in the carriage-frame, and having fixed at its upper end a pinion c", which meshes with a rack j, which is conveniently mounted on the guide-bar e. The rotation thus communicated from the shaft F through the gears f g g to the pinion 91' causes the latter, by engagement with the rack, to impart a traveling movement to the carriage in one direction or the other, according as the shaft F is turned in one direction or the other. Each carriage carries in a hearing at its top a transverse tubular shaft is, Figs. 3 and l, the shafts 7c k of the two carriages being exactly in line. end of this shaft are formed or fastened four (more or less) radial carryingarms G G. On its outer end is fixed a bevel-gear m. The bevel-gear h on the shaft h drives a bevelgear fixed on the lower end of a shaft Z, which turns within the tubular shaft t, and on the projecting upper end of this shaft is fixed a pinion m, which drives the gear m. Consequently as the carriage D advances the radial arms G G revolve.

The shafts F Fare driven by the drivingshaft F at the end of the machine through bevel-gears f f. The shaft F carries fast and loose pulleys n 'n' n, being driven in one direction or the other by two belts-the one direct and the other crossed-which are On the inner shifted alternately onto the fast pulleys by ,means of a belt-shifting device of ordinary construction, consisting of a rod o,'carrying two forks .and connected by a shaft 19, having elbow-arms o p, with a shipping-rod 1 extending longitudinally along one side of the vat, this rod carrying adjustable stops q q, to be encountered by the carriage at the opposite ends of its movement, and thereby to displace the rod q longitudinally, oscillate the shaft 19, and throw over the bar 0. As the latter passes the center, the completion of its movement is assured by the action of a spring 0 mounted on abar jointed toggle-fashion to the arm 0.

The construction thus far described does not differ to any material extent from that shown in my said previous patent, which also comprises traveling carriages with rotative shafts and sliding gearing for driving them, and each carriage carrying a transverse shaft with radial arms. The seizing devices carried by these arms, consisting in my former construction of coned disks for grasping the ends of the skeincarriers, are substituted in my new machine by essentially different devicesfor performing, although in a better manner, approximately the same function.

The devices for engaging and lifting the skein-carriers I prefer to designate as holders. These holders H H are carried by the ends of the carrying-arms G G. Each holder consists, according tothe preferred construction, of a shell or casting formed with two pockets opening at diametrically opposite sides of the holdernamely, a deep pocket 0' and a shallow pockets. The holder is mounted on a hollow shaft 25, which has bearings in the end of the arm G. (See Fig. 8.) The inner portion of the deep pocket ris made circular or cylindrical and concentric with the axis of this shaft, and within this concentric chamber is arranged a rotative boss or chuck J, which is mounted on a shaft 11., having bearings within the hollow shaft 15, Fig. 8.

The holders H H are constructed to be nonrotative during the revolution of the carrierarms G G. This may be accomplished in several ways, of which the most convenient is to connect them by epioycloidal gearing, as shown best in Fig. 7. To each holder is fixed a gear t,which meshes with an idler-gear t which in turn meshes with a stationary central gear 15 which is fixed on a central shaft 15 that passes through the upper end of the hollow shaft 70. The wheels t and 25 having both the same number of teeth the rolling of the idler planet-wheels 16 around the stationary wheel 15 communicates a relative backward rotation to the Wheels t at the same speed as the forward rotation of the arms G G, so that the wheels 6' and the holders remain non-rotative. By this means the holders H H always stand the same side up during the rotation of the carrying-arms, although they may he inverted at the end of that rotation, as will he presently described. In Fig.

7 they are shown with the top pockets 0' turned uppermost and in Fig. 12 with the shallow pockets .9 uppermost. Assuming the latter position, in which the action is more simple, the operation will be described. The speed oftravel of the carriages is such that while the arms G G are making one complete revolution the carriages advance the space of four notches in the bars I) b, or one notch to each carrying arm or holder. (If a different 11 umber of carrying-arms were provided, a diflerent relative speed would be necessary-for example, for six arms the carriage should advance six notches to a revolution.) As each arm in its revolution moves upwardly, its holder moves up directly beneath the end 0 of one of the skein-carriers, so thatits pocket 3 engages this end of the carrier, and as the other end of the carrier is simultaneously engaged by a holder on the opposite carriage the carrier is lifted bodily by theholders, as shown in Figs. 12 and 13. It is thus carried up and rearwardly-that is, in the opposite direction to the travel of the carriage-and downwardly in approximately the are of a circle, and as the two holders descend they bring the opposite ends of the carriers into coincidence with two empty notches in the bars I) 1), into which they drop the carrier, and descending beneath it leave it. suspended therein. This operation is performed successively upon all the carriers during the travel of the carriages from one end of the vat to the other. Thus each carrier is lifted, carrying its skeins partly out of the dye. Its skeins are dragged backwardly within the dye, and the carrier is redeposited, having thereby agitated the dye and placed the skeins in anew position without, however, shifting them around the carriers. At the end of the travel of the carriages the holders H II are automatically inverted, bringing them to the position shown in Fig. 7. To accomplish this they are turned simultaneously a half-revolution in either direction. This is easily done by givinga half-turn to the central gear-wheel 25 through its shaft 15 To this end a pinion zfi" is fixed on the opposite end of this shaft and meshes with teeth on a sliding rack-bar K, movable in bearings formed on the frame of the carriage. Just before the carriage reaches the end of its travel the end of this bar encounters and is stopped by a stop or buffer K, mounted on the fined frame of the apparatus. The continued movement of the carriage causes the pinion 25 to roll along this now stationary rack, thereby imparting to it a half-revolution. To insure that it shall complete its movement after passing over the first quarter, a weighted arm t is fixed to the shaft or pinion, the weight of which after passing the center is sufficient to complete the semi-rotation of the shaft even if the carriage should stop (by the action of the beltshiftingmechanism) before it has carried the pinion to the end of its movement against the rack. To prevent. any accidental movements of the rack (which would result in partial rotation or tilting of the holders II II which might be sufiicient tointerfere with their correct operation) I provide locking springs or catches d, fastened to the frame of the carriage and their free ends constructed to engage alternately with the rack, as shown in Fig. 1. Each spring is constructed with bevelcd ends projecting beyond the rack, so that it will first encounter the stop K and be pressed down thereby to release the rack, as shown in Fig. 1,before the latter encounters the stop.

The stops K are duplicated at the opposite ends of the apparatus, so that the shafts t" are turned a half-revolution in one direction at one end of the travel of the carriages, and are turned back to the same extent at the other end of their travel; hence the holders H H, which remain always the same side up during the travel of the carriages, are inverted at the end of their travel in one direction and are reverted at the end of their travel in the opposite direction. The inversion of the holders brings" their deep pockets 7' uppermost, so that in engaging the carriers the ends of the latter drop down to the bottom of these pockets, as shown in the crosssectioned portions in Fig. 7. The carrier ends are consequently entirely within the concentric portions or chambers of the pockets, and are confined at their opposite sides between the checks of the rotative chucks J J,

as best shown in Fig. 11. Immediately upon being lifted out of the notches in the bars I) b the carrier begins to be turned by the rotation of the chuck J, which revolves, preferably, in the same direction as the carrierarms G G, although this is not essential. The speed of rotation of the chucks is such that, by preference, a single rotation shall be imparted to the carrier from the time it is lifted out of one pair of notches until it is deposited in the other pair. If the rotative axis of the arms G G is arranged at the same height as the centers of the carrier ends, as in the construction shown,so that the carriers are picked up and redeposited when the carrying-arms are horizontahthe speed of the chucks J will be just twice that of the arms G G. A faster speed, however,is ad missible,so that the carriers might beturned over twice, oreven three or more times, durin g their displacement from one pair of notches to another. \Vith the proportions shown, however, a single revolution of the carriers is sufficient and preferable. The action of the chucks in turning the carrier ends within the concentric portions of the deep pockets is shown by dotted lines in Fig. 7 and more clearly in Figs. 10 and 11, in which latter figures the carrier has been turned a quarter-revolution, so that it stands in a horizontal plane. The top carrier in Figs. 7, 8, and 9 has been turned a halfrevolution. The rotative movement can be imparted to the chucks in several different ways, of which the preferable one is by means of epicycloidal gearing, as shown. On the ICC IIO

outer end of the chuck-shaft uis fixed a pinion to, which meshes with an idler-pinion 10 which in turn meshes with a gear-wheel u which is fastened fixedly to the carriageframe d, so as to remain always non-rotative. Thus during the travel of the carriages in the contrary direction to that first described the holders serve to pick up, transfer, and redeposit the skein-carriers in the same manner as before, but at the same time the chucks or turning mechanisms are rendered operative to effect the turning over of the carriers and consequently the lisage of the skeins. If the turning mechanism were rendered operative at all times, the carriers would be turned over in one direction during the travel of the carriages forward, and would be turned in the contrary direction during their travel backward along the vat. There would be, consequently,a lisage of the skeins first in one direction and then back in the reverse direction, bringing the same portion of the skeins again out of the dye as before, so that this portion would beinsufficiently dyed. Heretofore the direction and periods of the turning of the carriers to produce the lisage have been left to the discretion of the operator, who could throw the turning mechanism into or out of action at will. By my present invention this function is rendered automatic and independent of the care or discretion of the workman. Consequently the lisage of the skeins occurs only at every alternate displacement of the carriers, and occurs always in the same direction, so that the portion of the skeins which is out of the dye remains out for the same duration for all the skeins, thereby'insuring uniformity of dyeing.

In case of need the operator can invert the holders at any time by pressing down the spring d to release the rack K and then throwing over the weighted arm 15 As soon, however, as the carriages have traveled to two successive ends of their stroke,the automatic operation of this mechanism is automatically re-established.

The employment of traveling carriages moving along opposite sides of the vat, although the most convenient means for supporting and operating the mechanism for displacing the skein-carriers, forms no novel part of my present invention, (being already disclosed in my said previous patent,) and may be substituted by any suitable means for supporting and driving the displacing mechanism and the turning mechanism.

By the expression displacing mechanism as used in this specification I mean the holders H H and means for imparting to them the necessary revolving and advancing movements, whereby they are adapted to pick up the successive skein-carriers, transport them to a suitable distance, and redeposit them, or any other equivalent mechanism for accomplishing the same result, such, for example, as that shown in my said previous patent. So far as the broader features of my present invention are concerned this displacing mechanism may be greatly varied and is not essentially confined to the exact construction shown or any close approach thereto.

By the expression turning mechanism as I have used it broadly throughout this specification, I mean the chucksJ J and means for revolving them, so that during the displacement of the skein-carriers these chucks may engage them and turn them over one or more times, or any other or equivalent mechanism by which the skein-earriers may be turned over to perform the lisage of the skeins during the operation of displacing them, such, for example, as the mechanism for that purpose shown in my said previous patent.

The holders H H, as devices for seizing or engaging the ends of the skein-carriers, constitute a novel and important feature of my present invention. The throwing of the turning mechanism out of action by inverting the holders is also an important feature. The same may be said of the specific means for inverting and reverting the holders, and of other novel details of construction. It will be understood that it is notessential that the holders H shall be constructed to be turned one hundred and eighty degrees to bring the shallow pockets 8 into action, as these pockets might be constructed to open at any other angle relatively to the deep pockets, in which case the holders should be turned only to the extent of the intervening angle. It is also apparent that in lieu of separate radial arms G G continuous disks may be employed for carrying the holders.

By the construction of the skein-carriers shown in Fig. 5, being notched or serrated, they are adapted to separate the strands or filaments during the turning of the carrier. The carrier shown in Fig. 6 has plain straight edges instead of being thus notched.

At the end of the dyeing operation the skeins may all be removed simultaneously from the dye by connecting a Windlass or any suitable mechanism to the frame B in order to lift it bodily above the vat, so that the skeins may drain. Before thus lifting the frame the carriages should be moved to the extreme end of their travel and entirely beyond the skein-carriers, so that all of the skein-carriers shall have been deposited on the frame B. The carriages and holders in nowise interfere with thelifting of this frame.

My improved apparatus may be used not only in the dyeing of skeins, butin the bleaching and washing thereof, and for such purposes will have advantages which will be obvious to those skilled in the art.
